Lowest order constrained variation calculations and backflow effects in liquid3He

  • 20 Accesses

Abstract

Ground-state energy studies are carried out for liquid3He based on a correlated wave function which incorporates the Feynman-Cohen backflow correlation operator. Applying a lowest order constrained variation (LOCV) method, calculations have been performed for a number of realistic potentials. Our results indicate an improvement over those obtained by other LOCV calculations performed using the Jastrow ansatz and are in good agreement with other calculations involving higher order terms.
